This is common in small dogs and can be from the diet, stress or an infection. Usually when they are small with bloody diarrhea, it is recommend to see a vet as this can require hospitalization due to dehydration. It is unlikely the dye as this is more a myth with no science to prove so. Your vet can check for an infection and start medicine to help
